Today, I would like to discuss on how big infinity is. Have you ever think about this? Since I was 7 years old, I always asked my teachers what is the last number?

“It’s more than what you think”

I don’t satisfied with the answer. So, when I went to the secondary school, I asked my teacher the same question.

“The biggest number is Infinity”

But, I came out with another question! What is infinity? I want a value like ∞ = 99987654321082. I keep asking myself how big a number can be? *I feel like eating something sweet right now because I’M HAPPY*

INFINITY HAS NO END

Infinity is the idea of something that has no end.

In our world we don’t have anything like it. So we imagine traveling on and on, trying hard to get there, but that is not actually infinity.

So don’t think like that (it just hurts your brain!). Just think “endless”, or “boundless”.

If there is no reason something should stop, then it is infinite.

INFINITY DOES NOT GROW

Infinity is not “getting larger”, it is already fully formed.

Sometimes people (including me) say it “goes on and on” which sounds like it is growing somehow. But infinity does not do anything, it just is.

INFINITY IS NOT A REAL NUMBER

Infinity is not a real number, it is an idea. An idea of something without an end.

Infinity cannot be measured.

Even these faraway galaxies can’t compete with infinity.

INFINITY IS INFINITE

All of these numbers are “finite”, we could eventually “get there”.

But none of these numbers are even close to infinity. Because they are finite, and infinity is … notfinite!

USING INFINITY

We can sometimes use infinity like it is a number, but infinity does not behave like a real number. To help you understand, think “endless” whenever you see the infinity symbol “∞”:

For example: ∞ + 1 = ∞

Which says that infinity plus one is still equal to infinity. When something is already endless, we can add 1 and it is still endless. The most important thing about infinity is that:

–∞ < x < ∞

Where x is a real number

Which is mathematical shorthand for “negative infinity is less than any real number,
and infinity is greater than any real number”

Here are some more properties:

Special Properties of Infinity

∞ + ∞ = ∞

-∞ + -∞ = -∞

∞ × ∞ = ∞

-∞ × -∞ = ∞

-∞ × ∞ = -∞

x + ∞ = ∞

x + (-∞) = -∞

x – ∞ = -∞

x – (-∞) = ∞

For x>0 :

x × ∞ = ∞

x × (-∞) = -∞

For x<0 :

x × ∞ = -∞

x × (-∞) = ∞

Undefined Operations

All of these are “undefined”:

0 × ∞

0 × -∞

∞ + -∞

∞ – ∞

∞ / ∞

∞0

1∞

Example: Isn’t ∞ / ∞ equal to 1?

No, because we really don’t know how big infinity is, so we can’t say that two infinities are the same. For example ∞ + ∞ = ∞, so

∞∞ = ∞ + ∞∞

which
means that:

11 = 21

?

And that doesn’t make sense!

I could have also made 1=3 and so on … so we say that ∞ / ∞ is undefined.

Hye guys. It has been awhile since our last post. Do you guys miss us? Absolutely yes? Ohhh, i appreciate that as much as i appreciate my breakfast, lunch and my dinner *what to eat eh during breakfast tomorrow?🤔*

So today, I am going to share with you guys my subject for this semester. And as you guys know, my section involve in real life. So, I will update about the subject and its application in real life. Why we study these subject and how we gonna apply these subject in our daily life. I guess everyone is wondering why we take this subject and that subject. Have you ever wondered why we ate Nasi Lemak as our breakfast?🍛

I am currently in my forth semester. I am taking Vector Calculus, Probability Theory and Introduction to Analysis as my core subjects. What we can apply in the future?

Vector Calculus📚

Vector calculus. As you guys know, it is basically vector involving in direction and magnitude. Vector can be used in many field. It can be used in navigation of aeroplane, ship and satellite since it involved in direction, distance and coordinate. Vector also used in mechanics, physics and computer engineering. When it comes to calculus, a lot of things can be applied.

Ali wants to go to the shop to buy an ice cream for him and his younger sister, what is the distance from the house to the shop?

Probability Theory📚

This is what we learn since high school but university level is much more details and yet delicious. In high school we learn how to make the nasi for Nasi Lemak but in university, we start to learn how to make the sambal for Nasi Lemak, fry the nuts and chop the same size of cucumber.

Basically for me, probability theory can be applied a lot in real life. For instance, if you are an athlete for football, the chance you will win the game is 50-50.

A shopkeeper, selling cakes in her bakery. She will bake more highly requested cake which has more sale. The cake is the mode among other cake.

Sister, brother, and I are going to buy a dinner for Mother’s Day, then the average money each of us has to pay is the average. The average money is the mean.

10 people is lined up by age to buy a bowl of Laksa, the median age is the one who is lining up in the middle. So, the age of the middle person is the median.

Introduction to Analysis📚

Mathematical analysis and computational modeling are important for solving some of the most pressing problems of our time – new energy resources, climate change, risk management, epidemiology, to name a few. We must strive to maintain our technological edge; mathematical skills will be crucial to this effort.

In case you are wondering, why we as Mathematics students learn about all the theorems, lemma, corollary

I think I cleared many things to our blog reader and also to me as a Mathematics student. I hope everyone knows the importance of studying/learning Maths. As I grow older, people around me will ask the same question

“Why we learn Maths?”💆

“Why Maths make the students feel so burden with the questions?”💆

“How I can answer all of this questions?”💆

“Why we have to find x?”💆

Learn Maths is not something that you have to feel like it is hard. As I always said, Maths is fun. Your mindset is the most important things. Bad mindset will lead to negative result. Do learn Maths as fun as you eat your Naan Cheese with Tandoori Chicken.

Our final examination is around the corner, I hope there is a stall with delicious food at the corner. Till we meet again in our next blind date*It is a blind date because we interact only using this blog😍*

“It takes 4 weeks for you to notice your body changing. 8 weeks for your friends and 12 weeks for the rest of the world. Give it 12 weeks. Do not quit.”

You need mathematics in balanced diet. Believe it or not? If you are not using mathematic, then you really do not have any idea how much calories do you need each day. How to balance your diet and how to control the amount of food you take. Calories are the sum of food and drink you take every day and how you use the calories in your daily life.

Food + Drink = Calories

5 Golden Health Tips

1 Apple / Day = No Doctor

1 Tulsi Leaf / Day = No Cancer

1 Lemon / Day = No Fat

1 Cup Milk / Day = No Bone Problem

3 Liters Water / Day = No Diseases

What you need in a diet is really important. You have to know :

The quantity of food and drink that you need to take.

The interval of time like at what time you should eat you breakfast or lunch.

The ratio of consumption. For an example in one plate how many ratios that you have to take for vegetable, protein and carbohydrate.

Different people react with different calories. Usually men will take more calories than a woman since they need more energy to do work.

“In general, a moderately active 19-to-30-year-old woman needs 2,000 to 2,200 calories a day, whereas a man in the same category need 2,600 to 2,800.”
